Couldn't we have more than one choice? I like them all!
Ankylosaurus was cool tank looking guy, but he seemed always grumpy and angry. Everyone loves longnecks Stegosaurus was said to have a brain size of a walnut lol Always chose leafeaters before meateaters or sharptooths :<
I'll pick Parasaurolophus so I call out to people from a far " Heeeeey giiiirlfran!"
